DYE-APPLYING WHEEL.

Application filed January 18, 1924. Serial 1T0. 586,941.

To all whom it may concern:

Be it known that I, GEORGET. THOMAYER,

a citizen of the United States, and a resident of Albany, county of Albany, State of New York, have invented certain new and useful Improvements in Dye-Applying Wheels, of

which the following is a specification;

This invention relates to a dye applying wheel and, more particularly to a wheel suitable for use in yarn dyeing machines of the type shown in my .co-pending applications Serial Nos. 591,475, 616,901 and 619,097, now

Patents Nos. 1,488,297; 1,488,298; and

1,488,299, respectively, of which the present application is a continuation in part. i

In the machine of my above mentioned copending applications and similar machines, the yarn or thread being dyed is passed at a high speed over a dye supplying means supplied from a body of'dye liquor. The passing yarn or thread is tossed or swung at successive intervals into and',out of contact with the surface of the dye supplying means, such as a rotating wheel, picking up and absorbing the film or layer of liquor which has been carried up on the glrface of the wheel from the body of dye liquor. It is desirable that the dye liquor shall be given to, and absorbed by, the yarn readil and in a uniform manner, presentinga read ily absorbable film of the proper thickness to give the desired color to the yarn and avoiding uneven spots in the dyed portions.

lhis object is accomplished by my present invention which provides a means by which a uniform, thin film of dye liquor is continuously presented to be readily absorbed by the moving yarn.

Another object accomplished by the invention is to provide a dye wheel from which the dye liquor may be readily absorbed by the passing yarn without the necessity for rubbing or forcibly pressing the yarn on the dye wheel.

Another object of the invention is to provide a dye supplying wheelin which a film of liquor may be continuously replenished as it is absorbed from an exposed portion of the wheel.

With these and other objects in view the invention comprises the apparatus described and set forth in the following specification and claims.

The various features of the invention are illustrated inthe accompanying drawings in which: I

Fig. 1 is a cross sectional view of -a dye tank and. a side view of a dye applying wheel embodyin the invention, Fig. 2 is a p an view of the apparatus shown in Fig. 1, v

Fig. 3 is a side view, partly in section, ofthe dye wheel of the above figures, one of a number of dye holdin elements being shown partly withdrawn to illustrate the construction of the wheel, and,

Fig. 4 is a section of the wheel taken on line 44 of Fig. 3.

In my present invention, a film of dye liquor is carried up on the peripheral surface of a rotating wheel from a body of.

dye liquor in which the wheel dips to a position to be taken up by the passing yarn. .The peripheral surface of the wheel preferably flanged radially outwardly very slightly at its side edges so that these edge portions project very slightly above the portion touched'by the passing yarn, thus assisting in forming and maintaining a suitable film of liquor therebetween. The fonmation and maintenance of a film as the liquor .is being absorbed by the passing yarn is also facilitated by providing a number of pockets spaced in the periphery of the wheel and "filled with bodies of absorbent material adapted to soak up dye liquon when submerged-in the liquor and to supply the liquor tothe adjacent surfaces of the wheel when raised out of the liquor.

Referring more particularly to the accompanying drawings, a wheel 10 embodying the invention is shown in Figs. 1 and 2, mounted on a rotating supporting shaft 12 in a dye liquor tank 14 in such a position that the lower part .of the wheel dips into a body of dye liquor 16 in the tankwhile the upper part of the wheel projects through an opening 18 in the tank in position to be touched by passing yarn 20. As described in the applications mentioned above, the yarn is preferably guided through a pair of guides 22 and 24 on oppositesides of the tank and is intermittently thrown upwardly by a rotating cam or randomer 26 and permitted to fall downwardly into contact with the upper surface of the wheel A film of dye liquor. is thus carried from the liquor 14 to the upper surface of the dye wheel in position to be absorbed by the passing yarn. The peripheral surface of nance of a film of liquor to be absorbed, a

number of pockets 34 areformed in the periphery of the Wheel at spaced intervals and are filled with bodies of absorbent material 36 of felt or equivalent material, which act somewhat as sponges absorbing dye liquor from the body of dye liquor when submerged therein and providing a supply of the liquor to the adjacent surface of the wheel when in their upper positions. The pockets 34 are preferably formed by drilling holes radially inwardly into the wheel, the size and distribution of the holes preferably being such that adjacent holes meet at their inner ends, as at 38, thus joining all of the holes internally and enabling the adjacent bodies of fibrous materials to contact.

Through this invention, a film of the dye liquor is presented to passing yarn in such a manner that it may be readily absorbed without pressing or rubbing the yarn against within the scope of my invention it is in tended that all matter contained. in the above description or shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense.

Having described my invention, what 1 claim and desire to secure by Letters Patcm is: e

1. A dye applying wheel which comprises a solid disc having pockets in its periphery and masses of absorptive material in said pockets.

2. A dye applying wheel which comprises, a solid disc, having holes formed radially therein, and plugs of absorptive material in said holes.

3. A dye applying Wheel which comp-rises, a solid disc having holes bored radially inwardly from the circumference of the disc and meeting centrally, and plugs of felt in said holes.

4Q A dye applying wheel which comprises, a wheel having its peripheral edges each provided with a very slight radial flange and pockets at intervals in the surface between said flanges, and bodies of liquor absorptive material in said pockets.
